FOLH1 and adrenal cortex carcinoma: Our secondary goals were to correlate ligand uptake to immunohistochemical (IHC) PSMA-expression, to establish the diagnostic added value of 68Ga-PSMA-PET imaging over the current standard, to investigate the normal biodistribution of 68Ga-PSMA in ACC and SDC patients, and to investigate the difference in PSMA-ligand uptake between ADT-treated and ADT naïve SDC patients.
